This multi-cache is located in Pitäjänmäki. The total length you'll need to travel is under two kilometers.
This cache will require you to use those brains. It's meant to be a night-cache, but poor sports can probably figure it out during the day also, but the location of the cache should prevent you from going to the cache during office hours...
First, go to the coordinates above and look for a guiding light. Then go to the source of the light and find the even number for an important event on a door (two digits).
Now look at your watch. It's time to go in that direction.
The distance you must travel is equal to a very famous number relating to your previous stop. If you can't figure out the number, then seek for further assistance in the hint.
On the opposite side of the road at end of the line is a building that helps you find the way to a man's heart. Go behind this building and look for a place between two winds.
